• What defines good developer culture? [closed]

  - by Sven

  We are a team of 6 people developing applications for mobile devices (Android & iOS). In our company, which consists of many teams responsible for "classic" software development, business intelligence, virtualization, hardware, etc., we are kind of a small startup because we were the first to use agile methods like Scrum and we are open to new technologies and methods. Also our team is pretty young with me being the oldest with 30 years. We would like to further raise productivity and motivation and thus are currently collecting points which make up a good developer/hacker culture and which may be improved in our team/company. This can be points that we can either improve ourselves or have to pass on to management. I would like to know what in your opinion defines good, modern developer culture? What does developer culture consists of? For example is it clearly defined career opportunities geeky office benefits like trips to extraordinary conferences like WWDC or Google I/O ...

• Lubuntu upgrade to 13.04 killed sound with ALSA. How to troubleshoot?

  - by Sven

  After upgrading to 13.04 from 12.10 Lubuntu lost audio playback after unplugging usb soundcard (Polycom) and plugging it back in. Volume control was gray and leading to pulseaudio mixer (not installed) so I uninstalled the pulseaudio package. I also removed and reinstalled the alsa-base package. After restart I have the alsamixer back everything seemingly as usual(volume 100%, unmute) but every sound program gets me errors no matter what device I select. aplay -L: null Discard all samples (playback) or generate zero samples (capture) pulse PulseAudio Sound Server default:CARD=NVidia HDA NVidia, ALC662 rev1 Analog Default Audio Device sysdefault:CARD=NVidia HDA NVidia, ALC662 rev1 Analog Default Audio Device front:CARD=NVidia,DEV=0 HDA NVidia, ALC662 rev1 Analog Front speakers surround40:CARD=NVidia,DEV=0 HDA NVidia, ALC662 rev1 Analog 4.0 Surround output to Front and Rear speakers surround41:CARD=NVidia,DEV=0 HDA NVidia, ALC662 rev1 Analog 4.1 Surround output to Front, Rear and Subwoofer speakers surround50:CARD=NVidia,DEV=0 HDA NVidia, ALC662 rev1 Analog 5.0 Surround output to Front, Center and Rear speakers surround51:CARD=NVidia,DEV=0 HDA NVidia, ALC662 rev1 Analog 5.1 Surround output to Front, Center, Rear and Subwoofer speakers surround71:CARD=NVidia,DEV=0 HDA NVidia, ALC662 rev1 Analog 7.1 Surround output to Front, Center, Side, Rear and Woofer speakers iec958:CARD=NVidia,DEV=0 HDA NVidia, ALC662 rev1 Digital IEC958 (S/PDIF) Digital Audio Output hdmi:CARD=NVidia,DEV=0 HDA NVidia, HDMI 0 HDMI Audio Output dmix:CARD=NVidia,DEV=0 HDA NVidia, ALC662 rev1 Analog Direct sample mixing device dmix:CARD=NVidia,DEV=1 HDA NVidia, ALC662 rev1 Digital Direct sample mixing device dmix:CARD=NVidia,DEV=3 HDA NVidia, HDMI 0 Direct sample mixing device dsnoop:CARD=NVidia,DEV=0 HDA NVidia, ALC662 rev1 Analog Direct sample snooping device dsnoop:CARD=NVidia,DEV=1 HDA NVidia, ALC662 rev1 Digital Direct sample snooping device dsnoop:CARD=NVidia,DEV=3 HDA NVidia, HDMI 0 Direct sample snooping device hw:CARD=NVidia,DEV=0 HDA NVidia, ALC662 rev1 Analog Direct hardware device without any conversions hw:CARD=NVidia,DEV=1 HDA NVidia, ALC662 rev1 Digital Direct hardware device without any conversions hw:CARD=NVidia,DEV=3 HDA NVidia, HDMI 0 Direct hardware device without any conversions plughw:CARD=NVidia,DEV=0 HDA NVidia, ALC662 rev1 Analog Hardware device with all software conversions plughw:CARD=NVidia,DEV=1 HDA NVidia, ALC662 rev1 Digital Hardware device with all software conversions plughw:CARD=NVidia,DEV=3 HDA NVidia, HDMI 0 Hardware device with all software conversions default:CARD=Communicator Default Audio Device sysdefault:CARD=Communicator Default Audio Device front:CARD=Communicator,DEV=0 Polycom Communicator, USB Audio Front speakers surround40:CARD=Communicator,DEV=0 Polycom Communicator, USB Audio 4.0 Surround output to Front and Rear speakers surround41:CARD=Communicator,DEV=0 Polycom Communicator, USB Audio 4.1 Surround output to Front, Rear and Subwoofer speakers surround50:CARD=Communicator,DEV=0 Polycom Communicator, USB Audio 5.0 Surround output to Front, Center and Rear speakers surround51:CARD=Communicator,DEV=0 Polycom Communicator, USB Audio 5.1 Surround output to Front, Center, Rear and Subwoofer speakers surround71:CARD=Communicator,DEV=0 Polycom Communicator, USB Audio 7.1 Surround output to Front, Center, Side, Rear and Woofer speakers iec958:CARD=Communicator,DEV=0 Polycom Communicator, USB Audio IEC958 (S/PDIF) Digital Audio Output dmix:CARD=Communicator,DEV=0 Polycom Communicator, USB Audio Direct sample mixing device dsnoop:CARD=Communicator,DEV=0 Polycom Communicator, USB Audio Direct sample snooping device hw:CARD=Communicator,DEV=0 Polycom Communicator, USB Audio Direct hardware device without any conversions plughw:CARD=Communicator,DEV=0 Polycom Communicator, USB Audio Hardware device with all software conversions etc/asound.conf: defaults.ctl.card 1 defaults.pcm.card 1 defaults.pcm.device 1 Following gets same result with both devices. aplay -vv -D front:CARD=NVidia,DEV=0 "Release the Pressure.wav": Playing WAVE 'Release the Pressure.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Mono aplay: set_params:1087: Channels count non available Guayadeque mp3 playback: AL lib: alsa_open_playback: Could not open playback device 'default': No such file or directory 21:32:14: Error: Gstreamer error 'Configured audiosink playbackbin is not working.'

• Boots up into Terminal

  - by Jacob Larson

  I am running a 64 bit version of Ubuntu 12.04.1, and I when I boot up, I am thrown (Rather violently. :P) a full-sized terminal, instead of my lovely GUI login screen.. So I looked around and tried the "startx" command, which works like a charm. Only problem is that now, I have no clue how to keep it from booting to the terminal every time, and boot up into the regular GUI with all my stuff. I did install some kernel updates the night before, though I restarted my computer twice after I had done so without a problem. Thanks for your time!

• MiniMax function throws null pointer exception

  - by Sven

  I'm working on a school project, I have to build a tic tac toe game with the AI based on the MiniMax algorithm. The two player mode works like it should. I followed the code example on http://ethangunderson.com/blog/minimax-algorithm-in-c/. The only thing is that I get a NullPointer Exception when I run the code. And I can't wrap my finger around it. I placed a comment in the code where the exception is thrown. The recursive call is returning a null pointer, what is very strange because it can't.. When I place a breakpoint on the null return with the help of a if statement, then I see that there ARE still 2 to 3 empty places.. I probably overlooking something. Hope someone can tell me what I'm doing wrong. Here is the MiniMax code (the tic tac toe code is not important): /* * To change this template, choose Tools | Templates * and open the template in the editor. */ package MiniMax; import Game.Block; import Game.Board; import java.util.ArrayList; public class MiniMax { public static Place getBestMove(Board gameBoard, Block.TYPE player) { Place bestPlace = null; ArrayList<Place> emptyPlaces = gameBoard.getEmptyPlaces(); Board newBoard; //loop trough all the empty places for(Place emptyPlace : emptyPlaces) { newBoard = gameBoard.clone(); newBoard.setBlock(emptyPlace.getRow(), emptyPlace.getCell(), player); //no game won and still room to move if(newBoard.getWinner() == Block.TYPE.NONE && newBoard.getEmptyPlaces().size() > 0) { //is an node (has children) Place tempPlace = getBestMove(newBoard, invertPlayer(player)); //ERROR is thrown here! tempPlace is null. emptyPlace.setScore(tempPlace.getScore()); } else { //is an leaf if(newBoard.getWinner() == Block.TYPE.NONE) { emptyPlace.setScore(0); } else if(newBoard.getWinner() == Block.TYPE.X) { emptyPlace.setScore(-1); } else if(newBoard.getWinner() == Block.TYPE.O) { emptyPlace.setScore(1); } //if this move is better then our prev move, take it! if((bestPlace == null) || (player == Block.TYPE.X && emptyPlace.getScore() < bestPlace.getScore()) || (player == Block.TYPE.O && emptyPlace.getScore() > bestPlace.getScore())) { bestPlace = emptyPlace; } } } //This should never be null, but it does.. return bestPlace; } private static Block.TYPE invertPlayer(Block.TYPE player) { if(player == Block.TYPE.X) { return Block.TYPE.O; } return Block.TYPE.X; } }

• Unable to connect to iFolder server

  - by Sven

  I tried to install iFolder on Ubuntu 10.10 server 64 bit using this guide. Everything "worked" except: If I try to acccess the server with http://myurl/admin I get the error-message "Unable to connect to the iFolder server." Has anyone succeeded with this guide, or is there an iFolder specialist who could help me with the last steps? Update 1: I could connect to the /admin-Interface by not changin anything in the config-script. Changing the ServerName in anything else than localhost brings back the error. And changing username and/or password has no affect.

• EOL of MySQL Forge

  - by Keith Larson

  Forge was intended to be a community wiki resource for sharing information with each other.   However, over the last few years, we have seen Forge used less and less by MySQL Community, and more by spammers. What happened? MySQL Worklogs and MySQL Internals documentation will be moved to dev.mysql.com and with new anti spam measures in place. The MySQL Wiki, which was the primary focus of forge.mysql.com has been migrated to https://wikis.oracle.com/display/mysql MySQL Forge will EOL on August 1st 2012.

• Silverlight: AutoCompleteBox and TextWrapping

  - by Sven Sönnichsen

  How to enable TextWrapping in the AutoCompleteBox control of the SilverlightToolkit (November 2009)? There is no property to set the wrapping mode. So is there any workaround? Sven Here are more infos about my current problem: To me the AutoCompleteBox consists of a list which displays all possible values and a TextBox where I enter a search string and display a selected value. I want now, that the selected value in the TextBox wraps. So here is my current XAML, which uses the AutoCompleteBox in a DataGrid: <data:DataGrid x:Name="GrdComponents" ItemsSource="{Binding Path=Components}" AutoGenerateColumns="false" Margin="4" VerticalAlignment="Stretch" VerticalContentAlignment="Stretch" HorizontalScrollBarVisibility="Visible"> <data:DataGrid.Columns> <data:DataGridTemplateColumn Header="Component" Width="230"> <data:DataGridTemplateColumn.CellEditingTemplate > <DataTemplate> <input:AutoCompleteBox Text="{Binding Component.DataSource, Mode=TwoWay, ValidatesOnExceptions=True, NotifyOnValidationError=True}" Loaded="AcMaterials_Loaded" x:Name="Component" SelectionChanged="AcMaterial_SelectionChanged" IsEnabled="{Binding Component.IsReadOnly, Mode=OneWay, Converter={StaticResource ReadOnlyConverter}}" BindingValidationError="TextBox_BindingValidationError" ToolTipService.ToolTip="{Binding Component.Description}" IsTextCompletionEnabled="False" FilterMode="Contains" MinimumPopulateDelay="1" MinimumPrefixLength="3" ValueMemberPath="Description"> <input:AutoCompleteBox.ItemTemplate> <DataTemplate> <TextBlock Text="{Binding DescriptionTypeNumber}"/> </DataTemplate> </input:AutoCompleteBox.ItemTemplate> </input:AutoCompleteBox> </DataTemplate> </data:DataGridTemplateColumn.CellEditingTemplate> </data:DataGridTemplateColumn> </data:DataGrid.Columns> </data:DataGrid> The AutoCompleteBox uses different values for the list (DescriptionTypeNumer) and for the selected value (Description).

• SQL Server 2008 to Sybase Linked Server (x64) -- Provider and permissions issues

  - by Cory Larson

  Good morning, We're testing a new SQL Server 2008 setup (64-bit) and one of our requirements was to get a linked server up and talking to a Sybase database. We've successfully done so using Sybase's 64-bit 15.5 drivers, however I can't expand the catalog list from a remote machine (connecting to the '08 box with SSMS) without having my network account being added as an Administrator on the actual box and then using Windows Authentication to connect to the server instance. This is going to be problematic when we go live. Has anybody experienced this, or have any input on the permissions in SQL Server 2008 with regards to linked servers? If I remove my network account from the Administrators group, the big error I'm getting is a 'Msg 7302, Level 16, State 1, Line 41' with a description something like "Cannot create an instance of OLE DB provider "ASEOLEDB" for linked server "", and all research points to permissions issues. Thoughts? This document talks about DCOM configuration and permissions, but we've tried all of it with no luck. Thanks

• Change XRDP keyboard layout to en-gb Ubuntu 12.04

  - by Earl Sven

  Does anybody know how to change the keyboard layout to en-gb in an XRDP session on Ubuntu 12.04? I am using mstsc.exe to connect to an XRDP server hosting an XVNC session, however I cannot work out how to apply the UK keyboard layout. A bit of googling has yeilded these instructions which allow me to change the keymap, however using the keymap file I downloaded from here I loose the ability to use the arrow keys, home/end etc. Comparing the file with the standard one there are substantially more differences than I would expect considering the similarity between the layouts. I only have RDP access to the box so i don't seem to be able to actually generate a new layout per the instructions above, maybe it's a local console thing? Also I can't change either the RDP client used or the RDP server as they are my only access to the system, I don't have local console access. I do have root priveleges on the OS however. Any thoughts? Edit: I have found http:// xrdp.sourceforge.net/documents/keymap/newkeymap.html (apologies for not typing the link properly but the antispam filter won't let me post more than 2 links) this documentation on the XRDP sourceforge page which describes keymap file format. It indicates the values in the keymap files are unicode 0x64 etc, however the files I have already on my system seem to use a different format 0:0 or 65307:27 etc, does anybody know what the difference is?

• Password Policy seems to be ignored for new Domain on Windows Server 2008 R2

  - by Earl Sven

  I have set up a new Windows Server 2008 R2 domain controller, and have attempted to configure the Default Domain Policy to permit all types of passwords. When I want to create a new user (just a normal user) in the Domain Users and Computers application, I am prevented from doing so because of password complexity/length reasons. The password policy options configured in the Default Domain Policy are not defined in the Default Domain Controllers Policy, but having run the Group Policy Modelling Wizard these settings do not appear to be set for the Domain Controllers OU, should they not be inherited from the Default Domain policy? Additionally, if I link the Default Domain policy to the Domain Controllers OU, the Group Policy Modelling Wizard indicates the expected values for complexity etc, but I still cannot create a new user with my desired password. The domain is running at the Windows Server 2008 R2 functional level. Any thoughts? Thanks! Update: Here is the "Account policy/Password policy" Section from the GPM Wizard: Policy Value Winning GPO Enforce password history 0 Passwords Remembered Default Domain Policy Maximum password age 0 days Default Domain Policy Minimum password age 0 days Default Domain Policy Minimum password length 0 characters Default Domain Policy Passwords must meet complexity Disabled Default Domain Policy These results were taken from running the GPM Wizard at the Domain Controllers OU. I have typed them out by hand as the system I am working on is standalone, this is why the table is not exactly the wording from the Wizard. Are there any other policies that could override the above? Thanks!

• Can I make Gimp 2.8.4 in OSx make the file I just opened be the top window automatically?

  - by joe larson

  When I open an image file in Gimp 2.8.4 in OSx Mountain Lion 10.8.4 via the File Open menu, it does not automatically make that image the top window, requiring that I then find that window via the Window menu. Very jarring UX! Is there a way to modify this behavior so that it behaves like most GUI applications and brings the document just opened to the fore? Is this a bug in Gimp 2.8? Interestingly in my Ubuntu 12.04 with Gimp 2.6.12 this is not a problem. Since I haven't used Gimp much at all until this month, I don't know if this is a new problem or not.

• How to fix display on external Samsung Syncmaster shifted to the right when connected to Macbook Pro?

  - by joe larson

  Is there something special I need to do to be able to use external LCD displays with my new MacBook Pro? Do I need extra software, or do I possibly need a different cable? I'm attempting to use an external display with my MBP. I've got a "Mini DisplayPort to VGA Female Adapter for Mac", plugged into the thunderbolt port on my MBP, which I understood should be compatible with thunderbolt. I've tried this with three different SyncMaster models: a B2330 (21.5"), a EX2220 (22"), and a third (also 22" ish) which I don't have the model # for -- but all are 1920x1080 resolution; plus an additional HP monitor of similar size and resolution. In all four cases, the MBP recognizes the screen and choses the correct resolution. However, the display is shifted over about 1 inch. This is true no matter if I change screen resolutions also. The controls on the monitor for horizontal position don't help. Also, sometimes (especially if I drag an app over into the second screen), the screen starts skipping left to right and having bands of fuzz. Additionally, the monitor will periodically blink off for a moment, trying to switch from Digital to Analog and back (the Syncmaster shows text on the screen to tell you it's trying to do this). Often when it comes back from one of these blank-outs, it will show OK (no skipping or fuzz) but still shifted right; then after a few seconds it will go wrong again skipping and fuzzy. This photo shows the worst of it. I've added red rectangles to show the physical edge of the screen, and a yellow rectangle to show the empty space on the left of the screen. (Sorry for the awful quality and lighting!) Also, it's worth noting I am on Mac OS X 10.6.7, and yes I have this update 1.4 installed.

• How can I troubleshoot Virtualbox port forwarding from Windows guest to OSX host not working?

  - by joe larson

  There are a plethora of questions about virtual box port forwarding problems but none with my specific details. I have a Windows install living in Virtual Box, hosted within OSX. I've got several webservers running on localhost on different ports within the Windows install. I cannot for the life of me get port forwarding to work so I can access those webservers from OSX. My settings look like this (yes I have a NAT adapter): And in my vbox configuration file the relavent portion looks like this: <NAT> <DNS pass-domain="true" use-proxy="false" use-host-resolver="false"/> <Alias logging="false" proxy-only="false" use-same-ports="false"/> <Forwarding name="RLPWeb" proto="1" hostport="7084" guestip="127.0.0.1" guestport="7084"/> <Forwarding name="UtilWeb" proto="1" hostport="4040" guestip="127.0.0.1" guestport="4040"/> <Forwarding name="WCARLP" proto="1" hostport="8084" guestip="127.0.0.1" guestport="8084"/> <Forwarding name="WCAUtil" proto="1" hostport="4848" guestip="127.0.0.1" guestport="4848"/> </NAT> I've turned off the Windows firewall to ensure it is not interfering, and I am not running a firewall on OSX. Anyway, when I attempt to go to for example http://127.0.0.1:4040/ on any of my OSX browsers, it will eventually time out. The log file for this VM shows that it is correctly reading the settings and implying it's doing the right thing here: 00:00:08.286 NAT: set redirect TCP host port 4848 => guest port 4848 @ 127.0.0.1 00:00:08.286 NAT: set redirect TCP host port 8084 => guest port 8084 @ 127.0.0.1 00:00:08.286 NAT: set redirect TCP host port 4040 => guest port 4040 @ 127.0.0.1 00:00:08.286 NAT: set redirect TCP host port 7084 => guest port 7084 @ 127.0.0.1 00:00:08.290 Changing the VM state from 'LOADING' to 'SUSPENDED'. 00:00:08.290 Changing the VM state from 'SUSPENDED' to 'RESUMING'. 00:00:08.290 Changing the VM state from 'RESUMING' to 'RUNNING'. 00:00:08.337 Display::handleDisplayResize(): uScreenId = 0, pvVRAM=000000012017d000 w=1834 h=929 bpp=32 cbLine=0x1CA8, flags=0x1 00:00:09.139 AIOMgr: Host limits number of active IO requests to 16. Expect a performance impact. 00:00:13.454 NAT: DHCP offered IP address 10.0.2.15 I've tried setting the Host IP to 127.0.0.1, and I've tried setting Guest IP blank and also 10.0.2.15. None of these seem to help. What else can I look at to troubleshoot this issue? Details of setup: OSX 10.6.8 Windows 7 Professional 64bit VirtualBox 4.1.2

• Installing Git on Ubuntu 12.04

  - by Sven Jung

  I installed git with gitolite on my vserver using this tutorial. But I've got a problem to clone the gitolite-admin repo to my computer. The user is created with the option --disabled-password But if I try to clone with git clone git@<server>:gitolite-admin.git he asks not only for the passphrase of my rsa_key but also for the password of the gituser. Anyone an idea? I thought the user is created without password and I don't know what to type in

• User authentication -- username mismatch in IIS in ASP.NET application

  - by Cory Larson

  Last week, an employee's Active Directory username was changed (or a new one was created for them). For the purposes of this example, let's assume these usernames: Old: Domain\11111 New: Domain\22222 When this user now logs in using their new username, and attempts to browse to any one of a number of ASP.NET applications using only Windows Authentication (no Anonymous enabled), the system authenticates but our next layer of database-driven permissions prevents them from being authorized. We tracked it down to a mismatch of usernames between their logon account and who IIS thinks they are. Below are the outputs of several ASP.NET variables from apps running in a Windows 2008 IIS7.5 environment: Request.ServerVariables["AUTH_TYPE"]: Negotiate Request.ServerVariables["AUTH_USER"]: Domain\11111 Request.ServerVariables["LOGON_USER"]: Domain\22222 Request.ServerVariables["REMOTE_USER"]: Domain\11111 HttpContext.Current.User.Identity.Name: Domain\11111 System.Threading.Thread.CurrentPrincipal.Identity.Name: Domain\11111 From the above, I can see that only the LOGON_USER server variable has the correct value, which is the account the user used to log on to their machine. However, we use the "AUTH_USER" variable for looking up the database permissions. In a separate testing environment (completely different server: Windows 2003, IIS6), all of the above variables show "Domain\22222". So this seems to be a server-specific issue, like the credentials are somehow getting cached either on their machine or on the server (the former seems more plausible). So the question is: how do I confirm whether it's the user's machine or the server that is botching the request? How should I go about fixing this? I looked at the following two resources and will be giving the first one a try shortly: http://www.interworks.com/blogs/jvalente/2010/02/02/removing-saved-credentials-passwords-windows-xp-windows-vista-or-windows-7 http://stackoverflow.com/questions/2325005/classic-asp-request-servervariableslogon-user-returning-wrong-username/5299080#5299080 Thanks.
